This Is What Happens To Your Skin When You Start Taking Collagen Every Day After 40

Once you hit your 40s, you may start to notice your skin isn’t quite bouncing back like it used to. Fine lines become more noticeable, skin may feel thinner or drier, and that youthful plumpness slowly fades. While no single product can completely stop aging, esthetician Chris Gibson says there’s one daily habit that can make a visible difference: taking collagen peptides.
Collagen is the most abundant protein in the body and a key component of skin structure—it keeps skin firm, smooth, and resilient. “Collagen peptides are chains of amino acids,” explains Gibson. “They’re the building blocks the body uses to repair and regenerate tissues in the skin.” These peptides—made up of 19 amino acids—help form both collagen and elastin, the proteins responsible for skin’s strength and elasticity.
